Ultras White Knights said some of its members flew off the handle to contribute to Saturday’s unfortunate incidents which saw thousands of fans invade the pitch during Zamalek’s clash at home to Tunisia’s Club Africain.

It also said it would suspend its activities for an indefinite period to "reconstruct its structure."

The highly-charged match was called off in stoppage time after angry Zamalek supporters attacked Club Africain players, some of whom were injured during a free-for-all on the Cairo Stadium pitch.

According to the regulations of African governing body CAF, Africain will be automatically awarded a victory while Zamalek are likely to face heavy sanctions.

“We exerted lots of efforts to support Zamalek during the past four years, and even risked ruining our educational and professional future for the sake of our team,” Ultras White Knights said in a statement.

“We never had any plans to do anything inappropriate against Africain but we do not exonerate ourselves from responsibility because some of the group’s members inexplicably invaded the pitch.

“We apologize for all Zamalek fans, the Egyptian people, the Tunisian people and whoever was harmed because of the incident.

“The group announces that it is suspending its activities for an indefinite period.”
